The Austrian skydiver Felix Baumgartner has been frustrated in his attempt to make the highest ever skydive.
Unfavourable winds at Roswell, New Mexico, have prevented the launch of the helium balloon that was to take him to more than 120,000ft (36.5km).
Baumgartner - famous for jumping off skyscrapers - is hoping to become the first human to break the sound barrier unaided by a vehicle.
